Hi,

<div class = "center" contenteditable = "true" style = "padding-top: .5vh" id = "name"></div>

JS :

$( "#name" ).bind(  "keydown", function( e ) {
      if( e.which !== 8 && $( this ).text().length >= 16 ) {
        e.preventDefault();
        return false;
      }
      return true;
});

Regards,
